Hello John:
Nope. I reboot-ed Mathematica and the OS several times. When I tried to backup all my files since V7 was installed, some .nb files could not be copied. XP xcopy complained that they were "invalid directories" and that I should "run chkdsk". So something bad happened at some point. No evidence Mathematica caused this, but the usual suspects are *not* installed (i.e. VisStudio, Office, VPN S/W etc.).
Also, I found out the V7.0.1 link they sent to me [some weeks ago] was stale so I requested a refresh.
Regards..

I'd definitely recommend upgrading to 7.0.1 regardless. Did the problem go away when you restart Mathematica? A difficult-to-reproduce problem similar to this was reported in 7.0.0 which only lasted until you restarted the session. I don't recall the same problem having been reported against 7.0.1, although I wouldn't swear to it.
I wouldn't expect the loading of a Demonstrations notebook to cause any problems.
